SPECIFICATION forming eat of Letters Patent No. 638,405, dated. December5, 1s99. Application filed May 16, 1899- Serlal No. 716,998. (No model.)

T0 60 whom it may concern:

Be it known that I, EDWARD STERN, a citizen of the United States,residing at Boston, in the county of Suifolk and State of Massachusetts,have invented certain new and useful Improvements in Gas-HeatingSad-Irons; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to figures ofreference marked thereon, which form a' part of this specification.

My present improvements relate to a class of gas-heating sad-irons knownas short irons or those resembling in size and shape the ordinaryflat-iron in universal use and as distinguished from the long iron knownas a goose.

The object of this invention is to provide improved means for conductingthe current of heated vapor to the point most remote from thegas-burner, for regulating the air-supply, and for insulating the top ofthe iron.

To this end my invention consists in the construction and combination ofparts constituting a sad-iron, as hereinafter set forth and claimed.

The drawings accompanying this specification represent, in Figure 1, aside elevation, in Fig. 2 a vertical and longitudinal section, and inFig. 3 a vertical cross-section, of a gasheating sad iron containing myimprovements. Fig. 4 is a section, on an enlarged scale, of the burnerof-the gas-pipe and of the adjacent portion of the iron containing theair-mixing chamber, while Figs. 5 and 6 denote transverse Sections, alsoon an enlarged scale, of said chamber.

In the drawings the body of the iron is shown at 1 as of the old-timeflat-iron shape and size, the solid bottom thereof being shown at 2,while 3 represents a vertical wall surrounding the greater part of theboundary of the said bottom 2.

The top of the iron is shown at 2 as of practically equal shape and areawith the body 1.

The break or omission i in the boundarywall 3 provides ample space foradmission of air between the top and bottom of the iron. An additionalspace e of similar utility exists and screwing into the wall 3, whiletheir heads overlap the upper surface of the top. To provide furthermeans for circulation of air between the top and body of the iron, thewall 3 may be partially or entirely omitted at the rear end of suchbody, as shown at 7.

The wooden portion or hand-grasp of the handle of the iron is shown at 8and the upright curved arms which support such handgrasp at 9 9, thesearms at their base being cast integral with the top 2' of the iron.

The hand-grasp 8 is secured to the upper parts of the arms 9 9 by a boltll) passing through the three, and to protect the users hand from thehot metal I elongate the handgrasp and extend its ends over or about thehead of the bolt at one end and the nut which screws upon the oppositeend of such bolt.

The main purpose of the top 2 is to provide a means of support for thehandle and to protect the hand of the user from the heat of the flame.By delivering the flame directly upon the bottom of the iron thecomparatively small area of the bottom is quickly and thoroughly heated,while the inclined direction of the flame carries the latter forwardtoward the point of the iron.

The gas-supply pipe of the iron is shown at 11, the inner end of thispipe being inserted within the upper part of a tubular boss 12, formingpart of the rear arm 9 of the handle, the upper part of the interior ofthis boss constituting a chamber of greater area than the bore of thepipe. The chamber 13 connects at bottom with the space between the topand bottom of the iron by a passage 14, formed in part in the boss 12and in part in the said top. The inner end of the gas-pipe terminates ina burner 15, which enters the upper part of the chamber 13, and the wallofthis chamber is pierced with one or more air-inlet ports 16 16 toadmit of influx of air to such chamber and convert the gas issuing fromthe burner into a vapor of high temperature when ignited.

ICO

To govern the amount of air entering the mixing-chamber 13, or, as issometimes desirable, to entirely shut off the entrance of air, I employa sleeve or annular gate 17, which fits closely around the inclined boss12 and is adapted to be moved by hand up or down on said boss in thedirection of the length of the latter, so as to cover or uncover at willthe ports 16. A slot 17 ,lon gitudinal of the said boss, is formed inthe said sleeve or annular gate, and a clam ping-screw 17 passes throughthe said slot into the said boss to secure the said sleeve or gate inany position of such adjustment. The said screw always prevents the saidsleeve or gate from turning. For adjusting and holding it the screw isfirst loosened and tightened again after the sleeve has been moved topartly or wholly close the said ports. By raising or lowering the gate17 the ports 16 16 may be partially or entirely opened or closed.

To direct the flame issuing from the passage l-l to and upon the bottomof the iron and thence deflect such flame toward the front or point ofsuch iron, I cast a tubular inclined teat 18 upon the under side of thetop 2, the bore of this teat constituting the inner termination of thepassage 11. It will be seen that the passage 14 approaches the bottom ofthe iron at an angle (in present instance fortyfive degrees) tendingtoward the front of such iron, whereby the flame issuing from suchpassage is directed first upon the bottom and then toward or to thefront or point of said iron, thereby securin g a uniform temperature ofsaid bottom.

I claim- In combination with a hollow sad-iron body, a top plate andhandle fastened thereto, the said plate being provided with'a tubularteat 18 extending obliquely forward and downward, and one of thestandards of the said handle being provided with a similarly-directedpassage 14c continuous with the bore of the said teat, the wall of thesaid passage being extended upwardly and rearwardly beyond the rear ofthe said iron and provided with a lateral opening for air, an inlet atthe end of the said passage, and an adjustable ring or sleeve adapted tocover the said air= opening partly or wholly and thus regulate thesupply, substantially as set forth.
